The UP-A880 fully automatic ultraviolet oil analyzer is a professional instrument for achieving fully automatic measurement of petroleum in water. This instrument is fully developed in accordance with the standard of the People's Republic of China "HJ970-2018 Determination of Petroleum in Water Quality - UV spectrophotometry". It has stable performance, high accuracy, and fast detection speed, and is suitable for the determination of petroleum in surface water, groundwater, and seawater.

Principle:

The UP-A880 fully automatic ultraviolet oil analyzer extracts petroleum substances from water into n-hexane under pH ≤ 2 conditions. The extract is separated from oil and water, and then removed from polar substances such as animal and vegetable oils by a magnesium silicate adsorption column. The absorbance is measured at a wavelength of 225nm, and the petroleum content and absorbance values comply with Lambert Beer's law.

Reference standards:

HJ970-2018 Determination of Petroleum in Water Quality by UV spectrophotometry

Application areas:

Suitable for the determination of petroleum in surface water, groundwater, and seawater.

Technical advantages:

Purity testing of n-hexane: Fully automated n-hexane purity testing is completed, and sample testing can only be carried out after passing the test.

Independent cleaning position: Modular cleaning of inner and outer walls and the entire pipeline, effectively avoiding cross contamination.

Automatic switching of adsorption column: The magnesium silicate adsorption column can be automatically switched once for each sample detected, reducing cross contamination to the lowest possible level.

The measurement methods for standard samples and water samples are the same: when measuring standard samples or water samples, all samples are pre treated and sent to the host for measurement, and the results are displayed. To further verify the minimal impact of the preprocessor on the sample extraction results.

Product Features/Features:

High precision: using micrometer level precision screw to drive the grating, ensuring wavelength accuracy<± 0.5nm; The accuracy of transmittance is ± 0.3%.

High accuracy: The instrument has a high degree of automation, reducing human error and improving measurement accuracy and repeatability.

Fully automatic operation: Automatically completes processes such as n-hexane inspection, extraction agent addition, liquid-liquid extraction, oil-water separation, separation of animal and vegetable oils, petroleum measurement, pipeline cleaning, and automatic recovery of reagents.

Independent cleaning position: Modular cleaning of inner and outer walls and the entire pipeline, effectively avoiding cross contamination.

Automatic switching of adsorption column: The magnesium silicate adsorption column is automatically switched every time a sample is detected, reducing cross contamination to the lowest possible level.

Sample grade: freely set 1-N sample grades, can be measured non continuously.

Communication management: coexistence of wireless and wired, achieving seamless connection with computers, mobile terminals, and remote data platforms.

Safety and Health: The exhaust gas is adsorbed by an activated carbon adsorption column to prevent workers from coming into contact with n-hexane, and it is not suitable for use in fume hoods.

Remote control: can operate off-site, creating a new mode of detection.

Automatic separation of extractant and water sample: The instrument can automatically store extractant and water sample in different waste liquid bottles, reducing the amount of waste liquid treatment.

High extraction efficiency: The extraction efficiency is greater than 98% using the air blowing and jet extraction methods.

Fast analysis speed: The entire process only takes 5 minutes.
